Cleaning Daniel Defense M4A1 bolt carrier

[Carey1465]

First off, this is my first AR-15. I took the rifle to the range for the first time and shot 40 rounds to zero in the red dot. Took the rifle apart later to clean it and was a little confused after I finished wiping everything down. The bolt carrier and the assembly still looked dirty or it has a film on it. Here are some pics.

Should I scrub it a little more or this is normal?

New gun or just new to you?

Did you take it apart, clean, and lube it before the range visit?

Brand new gun. I took it apart the night before and it seemed to be oiled pretty good straight from the factory.

Looks ok to me

Oil everything and put it back together and go shoot. That is what a dry BCG looks like and will turn even black with oil.

Thanks for the replies. It looked dry cause I just finished cleaning it. It probably sounded like a stupid question but I thought it still looked dirty and didn't want to scrub to hard. Sooner or later should I invest in a nickel boron BCG? I've been watching videos online and it seems like that's the way to go.

No. DD makes a great BCG.

Yep, that's normal. My DD M4v11 bolt looks like that post cleaning pre oil

Will the black eventually wear off?

The black phosphate coating will begin to show wear, especially on either side of the gas key. Keep in mind with semi-auto's like AR's that oiling and lubing are not the same thing. Gun oil is typically at protecting the exterior finish of a firearm but those oils typically are too thin and burn off too quickly to provide adequate lubrication. Fireclean and SLIP2000 are my 2 favorite lubes for AR's. If you can't find those, Breakfree CLP is decent. Keep it wetter than you might think for long life and to minimize wear.
